WSP UV Water Sterilizer, Viqua

Why this happens

Bacteria and microorganisms can enter your well water from natural sources in the ground or from surface water seeping in. These tiny living things multiply in your water supply unless they’re treated somehow. The simplest way to check if your water has bacteria is a lab test for total coliform or E. coli presence. That test confirms whether your water needs disinfection beyond just filtering out sediment or minerals.

What it costs you to leave it untreated

Running water with bacteria means you spend more time boiling water or buying bottled water for drinking and cooking. It may make appliances that use water, like coffee makers, taste off or require more cleaning. You also risk blockages or corrosion in plumbing if biofilms develop. While it usually won’t damage your water heater directly, bacteria can cause unpleasant smells and affect your overall water experience in ways that are hard to ignore.

How this system fixes it

The WSP UV Water Sterilizer uses ultraviolet (UV) light to disinfect your water. As water runs through a stainless steel chamber, it is exposed to UV-C light. This light disrupts the DNA of bacteria, viruses, and cysts, making them unable to reproduce or cause illness. It’s a chemical-free way to reduce microorganisms, working continuously without changing your water’s taste or adding anything.

What this system can handle

The WSP UV Water Sterilizer comes in three flow rates: 9, 15, and 22 gallons per minute. The 9 GPM size suits smaller homes or systems with lower water use, while the 15 GPM is a common choice for average households. The 22 GPM model fits larger homes or light commercial applications where water demand is higher. It’s designed to handle well water with bacteria levels typical for private wells, maintaining steady flow while disinfecting effectively. The system works continuously and can treat water as it enters your home’s plumbing, protecting all taps and appliances downstream.

What you actually get

Each system includes a stainless steel UV chamber and a UV lamp designed to fit your chosen flow rate. The lamp produces UV-C light, the wavelength known for disinfection. There’s also a control module that monitors lamp operation and alerts you if the light is not working properly. The exact configuration depends on the size you select. Installation details and manuals come with your order to guide your plumber.

Is this the right size for you

Choose the 9 GPM unit for a small household with modest water use, such as 1–3 people. The 15 GPM is suitable for most families, supporting multiple bathrooms and daily water needs without slowing flow. If you have a larger household, several bathrooms in use at once, or a light commercial setup like a small office or guest house, the 22 GPM system is better to avoid flow restrictions. If you’re unsure, our sizing help can guide you to the right option before purchase.

Living with it

UV lamps need replacement roughly once a year because their disinfecting power fades over time, even if the lamp still lights up. The stainless steel chamber should be cleaned occasionally to remove any buildup that could block UV light. This maintenance is simple and costs little beyond the lamp itself. Your plumber can handle installation and annual lamp changes. No chemicals or filters need regular replacement with this system.

What it won’t do

The WSP UV Water Sterilizer reduces bacteria and microorganisms but does not remove sediment, iron, hardness minerals, or chemical contaminants. If your water has these other problems, you’ll need separate filtration or treatment systems. Also, UV does not store water or provide pressure—your existing plumbing must supply water at a steady rate.
